8. Don't fill the tank to its full capacity (the liquid injection volume does not exceed 80%
of the tank volume).
9. Even the duration is short, it must not exceed the maximum working pressure of
the tank.
10. After the completion of the tank filling and the end of the operation process, you
should make sure that the tanks and equipment should be removed quickly and all
closing valves in the equipment are closed.
11.The recovered refrigerants are not allowed to be injected into another system before
being purified and tested.
Note: The identification should be made after the appliance is scrapped and refrigerants
are evacuated. The identification should contain the date and endorsement. Make sure
the identification on the appliance can reflect the flammable refrigerants contained in this
appliance.
Recovery:
1.The clearance of refrigerants in the system is required when repairing or scrapping the
appliance. It is recommended to completely remove the refrigerant.
2.Only a special refrigerant tank can be used when loading the refrigerant into the
storage tank. Make sure the capacity of the tank is appropriate to the refrigerant
injection quantity in the entire system. All tanks intended to be used for the recovery of
refrigerants should have a refrigerant identification (i.e. refrigerant recovery tank).
Storage tanks should be equipped with pressure relief valves and globe valves and
they should be in a good condition. If possible, empty tanks should be evacuated and
maintained at room temperature before use.
3.The recovery equipment should be kept in a good working condition and equipped with
equipment operating instructions for easy access. The equipment should be suitable
for the recovery of R32 refrigerants. Besides, there should be a qualified weighting
apparatus which can be normally used. The hose should be linked with detachable
connection joint of zero leakage rate and be kept in a good condition.
Before using the recovery equipment, check if it is in a good condition and if it gets
perfect maintenance. Check if ll electrical components are sealed to prevent the
leakage of the refrigerant and the fire caused by it. If you have any question, please
consult the manufacturer.
4.The recovered refrigerant shall be loaded in the appropriate storage tanks, attached
with a transporting instruction, and returned to the refrigerant manufacturer. Don't mix
refrigerant in recovery equipment, especially a storage tank.
5.The space loading R32 refrigeration can't be enclosed in the process of transportation.
Take anti electrostatic measures if necessary in transportation. In the process of
transport, loading and unloading, necessary protective measures must be taken to
protect the air conditioner to ensure that the air conditioner is not damaged.
6.When removing the compressor or clearing the compressor oil, make sure the
compressor is pumped to an appropriate level to ensure that there is no residual R32
refrigerants in the lubricating oil. The vacuum pumping should be carried out before the
compressor is returned to the supplier. Ensure the safety when discharging oil from the
system.

Note: All the illustrations in this manual are for explanation
purpose only. Your air conditioner may be slightly different.
The actual shape shall prevail.They are subject to change
without notice for future improuement.
WARNING: This air conditioner uses R32 flammable refrigerant.
Notes: Air conditioner with R32 refrigerant, if roughly treated, may cause serious
harm to the human body or surrounding things.
* The room space for the installation, use, repair, and storage of this air conditioner
should be greater than 5 .㎡
* Air conditioner refrigerant can not charge more than 1.7kg.
* Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacturer.
* Not pierce or burn air conditioner, and check the refrigerant pipeline wether be
damaged.
* The appliance shall be stored in a room without continuously operating ignition sources
(forexample: open flames, an operating gas appliance or an operating electric heater.
* Notice that the refrigerant may be tasteless.
* The storage of air conditioner should be able to prevent mechanical damage caused
by accident.
* Maintenance or repair of air conditioners using R32 refrigerant must be carried out
after security check to minimize risk of incidents.
* Air conditioner must be installed with stop valve cover.
* Please read the instruction carefully before installing, using and maintaining.

3. Through blowing process, the system is charged into the anaerobic nitrogen to reach
the working pressure under the vacuum state, then the oxygen free nitrogen is emitted
to the atmosphere, and in the end, vacuumize the system. Repeat this process until all
refrigerants in the system is cleared. After the final charging of the anaerobic nitrogen,
discharge the gas into the atmosphere pressure, and then the system can be welded.
This operation is necessary for welding the pipeline.
Procedures of Charging Refrigerants
As a supplement to the general procedure, the following requirements need to be added:
- Make sure that there is no contamination among different refrigerants when using a
refrigerant charging device. The pipeline for charging refrigerants should be as short as
possible to reduce the residual of refrigerants in it.
- Storage tanks should remain vertically up.
- Make sure the grounding solutions are already taken before the refrigeration system is
charged with refrigerants.
- After finishing the charging (or when it is not yet finished), label the mark on the system.
- Be careful not to overcharge refrigerants.
Scrap and Recovery
Before this procedure, the technical personnel shall be thoroughly familiar with the
equipment and all its features, and make a recommended practice for refrigerant safe
recovery. For recycling the refrigerant, shall analyze the refrigerant and oil samples
before operation. Ensure the required power before the test.
1. Be familiar with the equipment and operation.
2. Disconnect power supply.
3. Before carrying out this process, you have to make sure:
â—ŹIf necessary, mechanical equipment operation should facilitate the operation of the
refrigerant tank.
â—ŹAll personal protective equipment is effective and can be used correctly.
â—ŹThe whole recovery process should be carried out under the guidance of qualified
personnel.
â—ŹThe recovering of equipment and storage tank should comply with the relevant
national standards.
4. If possible, the refrigerating system should be vacuumized.
5. If the vacuum state can't be reached, you should extract the refrigerant in each part of
the system from many places.
6. Before the start of the recovery, you should ensure that the capacity of the storage
tank is sufficient.
7. Start and operate the recovery equipment according to the manufacturer's instructions.
